Speccation of Letters Patent.

Application un nay s, 1907. serial No. 372,467.

'The details of construction, arrangement, and combination ol parts are as hereinafter described, and illustrated in the accompanying drawings, in which Figure l is a perspective view oi a horse-shoe constructed and provided with calks according to my invention. Fig. 2 is a section'on the line 2 2 oi Fig. l. Fig. 3 is a section on the line 3 3 of Fig. l. Fig. 4 is an inverted plan view oi a heel calk. Fig. 5 is a similar view showing a modification. Fig. 6 is an inverted plan View of a toe calk. Fig.l 7 is a plan view of one ol the heel portions of the shoe, the calk being detached. Fig. 8 is an end perspective o a calk.

As shown in Figs. l, 2, 3, a horse-shoe of the usual form is provided with bosses, or raised portions 1, 2, at the toe and heel, respectively. In each oi lsuch bosses there is formed, see Fig. 7, a groove 4ewhich is dove-tailed in cross-section and tapered from one end to the other. The Shanks-ot the toe and heel calks are correspondingly constructed; that is to say, the shanks 5 are dovetail shape in cross-section and tapered from end to end, and adapted toslide into the sockets 4'.

As shown in Figs. 4, G and 8, the shanks oi the heel and toe calks are slitted crosswise and lengthwise, as at (i, t3. Figs. l and S, thus forming practically two jaws or Wings. In place of the groove 6 extending the entire length of the calks, it may extend but a short distance as indicated at 6l' in Fig. 5.

When the calk is inserted in place, as indicated in Figs. 1, 2, 3, considerable force is required in order to ferr-e it to the required position, and this may be conveniently applied byl means of a hammer or other tool. When so inserted the taper of the calks and sockets prevents the former moving in one direction, and to prevent them sliding backward, or in the other direction and thus becoming loosened or detached the jaws `or wings formed at the smaller ends of the calks are spread hy means ot' a chisel, or other tapered tool, in sorted in the outer end of the slit or groove 6 or Gbd see dotted lines Figs. 5 and 6; The iiexibility of the metal permits this operation, and the form or flare thus imparted is retained and prevents the calk liecorning accidentally detached. The side i of the groove or socket 4 in the shoe proper are cut avt ay slightly at the smaller end, to form a space, permitting the free lateral expansion of the calk Shanks. The hold thus given to the calks is not, however, such as to prevent their being driven out of the shanks by means of -a hammer and punch or other tool which may be used for the purpose. Thus, it is at all times practicable to replace a broken or worn-out ealk by a new one.

In Fig. 1, I show a toe calk having tapered points 8 which are connected by a Wedge-shape bar 9 Whose height is about one-half that of the calk proper. By such construction and arrangement I provide the toe call: with an additional part for holding the shoe on the ground and also strengthen or support the points 8.

l claim- 1. A horseshoe provided with dove-,tail and tapered sockets whose smaller ends are enlarged laterally and calks having corresponding dove-tail and tapered Shanks adapted to said sockets so that when driven they wedge therein, the shrinks having :i lengthwise slit extending inward from the smaller end, thus forming expansible jaws, as and for the purpose spcciiicd.

2. A horse-shoe proper having; a dovetail and tapered socket, a calk having a corresponding shank adapted to wedge therein, and having,r its smaller end provided with vertical and transversev ,slits thus forming yllexihle jaws which are spread laterally arid engage the shoe, ns shown and described.

3. A horse-shoe having; u dovctnil and tapered socket, a calk havingr a shank of corresponding shape and size and provided ai. its smaller end with a slit dividing it into two jaws or wings which are expanded laterally, as shown and described.
